{"product_id":"tjernlund-pai-3-commercial-combustion-air-in-forcer","title":"Tjernlund PAI-3 Commercial Combustion Air In-Forcer","description":"\u003cspan style=\"font-size: 12pt; \"\u003eThe In-Forcer can be ducted up to 100 equivalent feet from the intake hood. Even isolated mechanical rooms can be easily supplied with outdoor combustion air. Cold outdoor air can be distributed through standard ducts and diffusers at ceiling level, allowing the air to be tempered as it drops to the floor, eliminating cold spots in the Mechanical room. Mechanical room noise transfer to the outside is further reduced since there is no direct wall opening, typical of standard louvers.\u003cbr\u003e \u003cbr\u003e \u003cspan style=\"font-weight: bold; font-size: 12pt;\"\u003eAPPLICATIONS\u003cbr\u003e \u003c\/span\u003e\u003c\/span\u003e\u003cul style=\"\"\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003eRestaurant kitchens with negative pressure caused by exhaust fans\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003eInterior mechanical rooms with no direct access to an outside wall\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003eConversions from electric to gas or oil heating appliances\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003eLaundries, dry cleaners, indoor pools, etc. with chemically contaminated atmosphere\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003eConfined space installations\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003eBelow grade mechanical rooms\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003eFactories where processes cause back drafting of heating euipment\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003cspan style=\"font-weight: bold;  font-size: 12pt;\"\u003e\u003cbr\u003e RESOURCES\u003c\/span\u003e\u003cbr style=\"\"\u003e \u003c\/span\u003e\u003cul style=\"\"\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003ca href=\"http:\/\/www.tjernlund.com\/Tjernlund_8500402.pdf\"\u003eTjernlund PAI-3 Brochure\u003c\/a\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003ca href=\"http:\/\/www.tjernlund.com\/Tjernlund_8506003.pdf\"\u003eTjernlund PAI-3 Specifications\u003c\/a\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003ca href=\"http:\/\/www.tjernlund.com\/Tjernlund_8504036.pdf\"\u003eTjernlund PAI-3 Installation Instructions\u003c\/a\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e \u003cimg style=\"width: 741px; height: 472px;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0785\/5895\/3645\/files\/Tjernlund_-_PAI3_-_Illustration.jpg?v=1788404080\" align=\"\" border=\"0px\"\u003e","brand":"Tjernlund","offers":[{"title":"Default Title","offer_id":47344106602669,"sku":"47927","price":560.77,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/5895\/3645\/files\/TjernlundPAI3.jpg?v=1787902759","url":"https:\/\/www.bostonheatingsupply.com\/products\/tjernlund-pai-3-commercial-combustion-air-in-forcer","provider":"Boston Heating Supply","version":"1.0","type":"link"}
